This episode of the Long COVID Clinical Podcast, hosted by Drs. Anita Chopra, Andrew Schamess, and Aaron Friedberg, features Dr. Nisha Viswanathan, internist and director of the long COVID Program at UCLA. The discussion delves into the complex relationship between long COVID and dysautonomia, including the distinctions between orthostatic intolerance, postural orthostatic tachycardia syndrome (POTS), and hyperadrenergic POTS. Dr. Viswanathan describes practical diagnostic tools such as the COMPASS 31 questionnaire and NASA Lean Test, and explores effective management strategies, including salt and fluid intake, and medications like fludrocortisone, beta blockers, and ivabradine. The conversation also touches on the overlap with conditions like ME-CFS and mast cell activation syndrome, and highlights upcoming treatments and research that promise to transform care for post-viral autonomic syndromes. The episode concludes with a focus on providing primary care physicians with actionable insights to improve patient outcomes in long COVID.
